Referring to the drawings, ,A represents the improved stackerVcomprising theihay `container 1B, platform C, and. loader D4operatively.connected together. The container B consists of the sideand fback ymembers 10 'and 11, `the former of which areformed of the twosections 12. and'13. 'and thelatt'erthe two sectionsA 14 and 15 slidablyconnected together, theback vand side members :being hinged taslshownrat 16.

H

Thisff-rameis also provided-on its `front end with, lorackets,38l whichAhinged-ly support the-.doors 39 connected Aaft, the. front zend bytherloridle-LO tothehaulingrope 41.'. y rl-hi's bridle is providedY witha roller 'or block 42 with which thejghanling ropefl enl-gages, the saidfhaulingrope extending over the ,1 pulley A3. mounted ion lthefyb acl;Lmember 11 intermediate of the ends thereof and then passing around thepulley 44, mounted on kthe lower end of the said back member, the freeend of the hauling rope being designed to be attached to the horseorlike y traction means which draws the loader D up over the platform C toengage with the skids 20 and so deposit the load of hay in the containerB. The loader D is returned to its loading position by the spiral springV45.

r1`he hay is primarily collected by the sweeps E which consists of aframe 46 provided with a plurality of equidistantly ily understood fromthe foregoing description.

lWhen the machine is in use the back and side members 11 and 10 of thecontainer B are extended to the desired extent and if it is founddesirable the side members may be angularly disposed by rotating themabout the hinges 16 and when the container has been arranged in thedesired position the stays 18 are engaged with the ground to prevent thelateral displacement of the side members 10.

rlhe hay collected by the sweeps E is delivered to the'y loader D andwhen the tractive force has been applied to the hauling rope 41 theloader is pulled up over the fingers 34 and platform C to engage withthe skids 20 and due to the fact that these skids are spaced apart thehay is deposited lbetween the same into the container.

l/Vhen the loader D engages with the skids 20 the said skids aredepressed at their rear ends and so pack the hay forming the stack andafter the load has been dumped from the loader 'the springs 21 willelevate the skids and return the loader D under the action of gravity toits normal position.

As the loading of the container B proceeds the rea-r end of the platformC is elevated by the exible member 27 while the rear ends of the skids2,0 are elevated by the flexible member 22 and the said members assumethe position shown by the dotted lines in Fig. l 1n this position thehauling rope 41 engages with the roller 33 mounted on the rear end ofthe platform C so that the said hauling rope is adequately guided 'andwill not in any way foul with the stack being formed or any other partof the machine.

During the operation of elevating the platform @the staples 25 engagingwith the weaves rods 26 prevent the rear end of the platform frombecoming displaced laterally.

It will be understood .that the container B is bottomless so thatA afterthe stack has been formed the platform C can be readily disengaged fromthe container which is then removed from the stack themachine being thenI taken to another part of the field preparatory to building a newstack.

From this description it will be seen that I have invented a haystackerwhich `can be advantageously utilized by farmers and wherein thestacking is mechanically performed, the hay being uniformly formed overthe stack and automatically packed during the process of building. v

As many changes could be made in the above construction, and manyapparently -widely different embodiments of my invention, within Vthescope of the claims, constructed without departing from the spirit orscope thereof, it is intended that all .matter contained in theaccompanying specification and drawings shall be interpreted asillustrative and not in a limiting sense. Y
